* media: rtl28xxu: fix idle handlingSean Young2019-10-071-0/+2
| | | | | | | | | | | | | | | | Currently the IR receiver is put into idle mode after each interrupt. However longer IR like NEC can be distributed over multiple interrupts, so putting the IR into idle in the middle of such a message will break decoding. Every IR message has a trailing space of 0xbf (one less than IR_IDE_LEN{0,1} which is programmed to 0xc0). So, set the timeout to that value and rc-core will put the IR receiver into idle mode automatically. Thanks to Jan Pieter van Woerkom <jp@jpvw.nl> for providing the hardware.

* [media] dvb-usb-v2: create one media_dev per adapterMauro Carvalho Chehab2015-02-261-4/+0
| | | | | | | | | | | | Instead of assuming just one adapter, change the code to store one media controller per adapter. This works fine for dvb-usb, as, on all drivers here, it is not possible to write a media graph that would mix resources between the two different adapters.

* [media] rtl2832u: restore ir remote control supportRodrigo Tartajo2013-06-081-1/+1
| | | | | | | | | | | | | | Hi, This patch uses the driver from openpli[1] as a template to restore the remote control support. I had to divert from the original to use the in kernel rc protocol decoder. The key repetition does, not seem to work but I cant find the problem in the driver. As a raw rc provider, no key table is hardcoded. Rodrigo.

* [media] rc-core: add separate defines for protocol bitmaps and numbersDavid Härdeman2012-10-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RC_TYPE_* defines are currently used both where a single protocol is expected and where a bitmap of protocols is expected. Functions like rc_keydown() and functions which add/remove entries to the keytable want a single protocol. Future userspace APIs would also benefit from numeric protocols (rather than bitmap ones). Keytables are smaller if they can use a small(ish) integer rather than a bitmap. Other functions or struct members (e.g. allowed_protos, enabled_protocols, etc) accept multiple protocols and need a bitmap. Using different types reduces the risk of programmer error. Using a protocol enum whereever possible also makes for a more future-proof user-space API as we don't need to worry about a sufficient number of bits being available (e.g. in structs used for ioctl() calls). The use of both a number and a corresponding bit is dalso one in e.g. the input subsystem as well (see all the references to set/clear bit when changing keytables for example). This patch separate the different usages in preparation for upcoming patches. Where a single protocol is expected, enum rc_type is used; where one or more protocol(s) are expected, something like u64 is used. The patch has been rewritten so that the format of the sysfs "protocols" file is no longer altered (at the loss of some detail). The file itself should probably be deprecated in the future though.
